AppScale 3.4 Released

The AppScale team is excited to announce the availability of AppScale 3.4! This release contains new features, additions to the API, performance improvements, upgrades for dependencies, and bug fixes.

A key new feature is the ability to deploy and manage multiple services (formerly known as modules). App Engine applications were initially based on one frontend instance and multiple backend instances, but introduction of GAE services allowed for more flexible microservices-style deployments. With version 3.4, services can be used in AppScale, too, in addition to old-style frontend/backends.

3.4 brings a revamped AppScalefile format, which will enable further improvements we have planned. Changing how nodes are associated with AppScale services makes for clearer, shorter, more readable configurations, especially for large installations. Changes in option names will also make AppScalefiles easier to read. For now, we’ll maintain backward compatibility: old syntax will be accepted.
